Skimming the last few posts I see other posters' remarks corroborating my own experience with TE--it took me about 6 months of never playing before the symptoms finally went away on their own. That's how long it took my body to heal itself of the TE that I am positively convinced I acquired solely by using polyester strings in my newer Prestige. Same frame a year later only this time it has a full be soft nylon instead of even just half a bed of poly and, voila, I have had no arm issues whatsoever since making the switch.
